JAMES J. MODONOUGH, OF ABINGTON, MASSACHUSETTS.

BEDSTEAD.

SPECIFICATION forming part of Letters Patent No. 713,666, dated November18, 1902.

Application filed December 27, 1901. Serial No. 87,459. (No model.)

To aZZ whom, it may concern:

Be it known that 1, JAMES J. McDoNoUoH, a citizen of the United Statesof America, and a resident of Abington, Plymouth county, and State ofMassachusetts, have invented certain new and useful Improvements inBedsteads, of which the following is a specification.

My invention relates to bedsteads of the type or class in which the bedproper is supported by a suitable spring or slat carrying frame, in turnsupported by other springs or analogous means.

In bedsteads of the kind just referred to it has been usual, so far as Iam aware, to mount the frame-supporting springs in or directly upon theposts of the bedstead. There are practical objections or disadvantagesto such former devices. Forexample,the thus mounted bed-carrying frameis not capable of a sufficient degree of vertical movement. The framemust be maintained in a substantially true horizontal position in orderthat it may move in a comparatively free manner, as otherwise thesupporting guides become cramped, thus seriously affecting theefficiency of the device.

The object I have in view or seek to attain is to produce a bedstead inwhich the disadvantages above referred to are overcome, the bed-framebeing so supported that it is capable of movement with a minimum degreeof friction. It is self-adjusting in that the device works freely, eventhough the load or weight upon the bed be very unevenly distributed.Another advantage possessed by my improved bedstead is that the workingstrains or forces are mainly borne by upper ties or braces attached tothe upper ends of the posts of the bedstead in such manner that thelatter is additionally strengthened and given greater rigidity, all aswill be more fully hereinafter set forth and claimed.

In carrying out myinvention I provide each of the head and foot membersof the bedstead with a vertically-slidable frame suspended from a strongyielding connection fixed to a diagonal tie or brace secured overhead tothe four posts of the bedstead. The said end frames are provided withsuitable means for supporting the usual bed or slat carrying frame. Asthus constructed the front and rear sides of the bedstead are whollyfree and unobstructed.

In the accompanying sheet of drawings, Figure 1 is a side elevation of abedstead embodying my improvements, the mattress and bedding beingomitted. Fig. 2 is a corresponding end view. Fig. 3 is a plan View. Fig.4 is a horizontal sectional view, enlarged, taken on line we of Fig. 2.

A, again referring to the drawings, designates my improved bedstead as awhole. I may state that bedsteads of this class are usually made ofsuitable metal, as brass, iron, the. The four corner-posts a of thebedstead are suitablyconnected together at or near thebase by side andend ties b b or in any other wellknown manner. The posts extend to aconvenient height and are provided at the top with a diagonal tie orbrace c, the ends of which are secured to the respective ends of theposts. The said member 0 forms a strut as well as a tie, therebyinsuring that the posts are prevented from lateral movement. Betweeneach pair of end posts is arranged a verticallymovable frame d, havinginwardly-extending horizontal pins or members d at its lower end forsupporting a slat-carrying frame or bedspring 6, as indicated by dottedlines in Fig. 1. Each of said frames d is suspended from a flexibleconnectionf, extending upwardly and over a freely-turning idler-sheave sand is secured to a helical spring or yielding connection f, in turnfirmly secured to said top brace c, as indicated in Fig. 8, said sheavesbeing mounted on upper ties s, as shown.

The frames 61 are guided in suitably constructed and arrangedfreely-turning flanged rollers h, mounted in clips or brackets 2',secured to the posts a. (See Fig. 4..) The said rollers h may be made ofrubber or other nonresonant material, thereby rendering the movements ofthe apparatus practically noiseless.

WVhile I have represented my improved bedstead in its simplest form, itis obvious that without departing from the spirit of the invention theshape and proportion thereof may be materially changed, as well as beingmade quite ornamental, if desired.

I claim as my invention and desire to secure by United States LettersPatent- In a bedstead,the combination with the four sheaves 8 havingsaid connections supported corner-posts thereof rigidly secured togetherthereon, all constructed, arranged and adaptat the bottom, of theoverhead diagonal tie ed for operation substantially as shown and member6 arranged to firmly secure the said described. 5 posts together at thetop of the bedstead, a Signed at Providence, Rhode Island, this 15 iguided vertically-movable bed-supporting 21st day of December, 1901.
